Summary: Is This the One for You?
Why choose it: You can prepare a stand and a knife and want to slice it yourself to your preferred thickness, and you expect to finish about 7 kg. If those two are your conditions, this product is a candidate (weak points: the rating is 5th of 7, and no stand is included).
- The total is about 7 kg, more than the other 6 (100 g–1,100 g), and the page says it arrives chilled with a best-before date of 30 days or more after delivery
- The Rakuten rating is 4.49 / 5 (196 reviews). Among the 75 we read, reviews mentioning repeat purchases (about 38) stood out. On the other hand, 8 reviews each mentioned differences between pieces, mold or smell, and the effort of slicing and storage
Other options: If you would rather start with a smaller amount, there is Raw Ham Mini Genboku (Andalusian Pork) (250 g, 300 g, 350 g); if you want to compare several kinds in small amounts, there is the Iberico Pork Raw Ham 5-Kind Tasting Set (100 g in total).
